Title:
TWO-PHASE FLOW TURBINE AND HEAT PUMP SYSTEM
Document Type and Number:
Japanese Patent JP2021085368
Kind Code:
A
Abstract:
To suppress brake loss of a two-phase flow turbine which is caused by a droplet scattered from a rotor vane and rebounding to the rotor vane from a casing in a two-phase flow turbine.SOLUTION: A two-phase flow turbine driven by a fluid including a liquid phase and a gas phase includes: a rotation shaft provided so as to be rotatable; a rotor vane 32 provided at a peripheral surface of the rotation shaft; and a casing 40 having an opposite surface which is opposed to a chip side 38 connecting a forward edge-side tip end 34a of the rotor vane to a backward edge-side tip end 36a via a clearance c. At least part of the opposite surface includes an inclined surface 42 inclined in a direction of which diameter expands toward a backward edge 36 from a forward edge 34 of the rotor vane.SELECTED DRAWING: Figure 3
